Angiomyolipomas (AML) are generally known as benign tumors. The kidney is the most common location of this tumor, and the liver is reported as the second most common site. Occurrence in other tissues is extremely rare. For instance, some cases of AML originating from the nasal cavity have been previously reported. We describe an AML case arising from the nasal cavity of a 56-year-old man. The patient had been complaining of nasal obstruction and foreign body sensation in the nasopharynx and was initially treated with preoperative angio-embolization. AML was then totally removed by endoscopic surgery without complications. He has been asymptomatic and has had no evidence of recurrence for 2 months after surgery.

PURPOSE: To report the initial clinical outcomes of the newly devised sliding loop technique (SLT) used for renorrhaphy in patients who underwent robot-assisted laparoscopic partial nephrectomy (RALPN) for small renal mass. MATERIALS AND METHODS: We reviewed the surgical videos and medical charts of 31 patients who had undergone RALPN with the SLT renorrhaphy performed by two surgeons (CWJ and CK) between January 2014 and October 2014. SLT renorrhaphy was performed after tumor excision and renal parenchymal defect repair. Assessed outcomes included renorrhaphy time (RT), warm ischemic time, perioperative complications, and perioperative renal function change. RT was defined as interval from the end of bed suture to the renal artery declamping. RESULTS: In all patients, sliding loop renorrhaphy was successfully conducted without conversions to radical nephrectomy or open approaches. Mean renorrhaphy and warm ischemic time were 9.0 and 22.6 minutes, respectively. After completing renorrhaphy, there were no adverse events such as dehiscence of approximated renal parenchyma, renal parenchymal tearing, or significant bleeding. Furthermore, no postoperative complications or significant renal function decline were observed as of the last follow-up for all patients. The limitations of this study include the small volume case series, the retrospective nature of the study, and the heterogeneity of surgeons. CONCLUSIONS: From our initial clinical experience, SLT may be an efficient and safe renorrhaphy method in real clinical practice. Further large scale, prospective, long-term follow-up, and direct comparative studies with other techniques are required to confirm the clinical applicability of SLT.

PURPOSE: To acquire the useful diagnostic information through the analysis of the clinical and radiological characteristics of mandibular unicystic ameloblastoma. MATERIALS AND METHODS: The researchers compared and analysed the clinical and radiological features of 79 cases of mandibular unicystic ameloblastoma confirmed by histopathlogic examination. RESULTS: The results of our research showed that unicystic ameloblastomas occurred more frequently in males than in females and the incidence is the highest in the 2nd and 3rd decades. These lesions occurred most frequently in angle-ramus area, mandibular molar area, and anterior area in descending order respectively 68.4%, 24%, and 7.6%. These lesions had smooth (54.4%) rather than undulating (45.6%) borders. These lesions showed welldefined borders in 59.5% among all the cases. Root resorption and loss of lamina dura were observed as 55.7% and 58.5% respectively. Displacement of mandibular canal was observed in 55.9% among all the related cases. Internal pattern of lesional radiolucency was observed as even (49.4%) or uneven (50.6%). CONCLUSION: These results would be helpful in diagnosing of mandibular unicystic ameloblastoma.

Hyperthyroidism is a well known cause of atrial fibrillation. It is also known that control of hyperthyroidism can usually curb thyrotoxic atrial fibrillation and restore sinus rhythm. In this study, 282 patients with hyperthyroidism were investigated to quantify the incidence of atrial fibrillation, and to identify the vulnerable groups. In addition, we compared two groups of subjects with atrial fibrillation-one group with hyperthyroidism and the other group without

Glomus tumor, a rare benign vascular tumor arising from the neuromyoarterial apparatus, is usually located at the tip of digits, especially at subungual region. Most of this tumor present typical symptoms such as hypersensitivity to cold, severe pain and point tenderness but frequently misdiagnosed as neuroma, gout or causalgia. Concerning about the origin of the glomus tumor, there were few written reports about extra-digit vascular origin glomus tumor especially that occurred at forearm artery. Recently we experienced a glomus tumor which arised at forearm radial artery and reported with review of literatures. A 31-year-old female admitted to our department with pulsating, slow growing, tender mass at her left forearm for about 1 year. After diagnostic evaluation of ultrasonography and magnetic resonance angiography, surgical resection was performed under the diagnosis of radial artery aneurysm but the histologic final diagnosis made by special immunohistochemical stains was glomus tumor originated from radial artery. The postoperative course was uneventful up to 2 years of follow up.

OBJECTIVES: A positive association between serum albumin levels and metabolic syndrome has been reported in observation studies, but it has not been established in the Korean population. The purpose of this study was to evaluate the association between serum albumin levels and the presence of metabolic syndrome among a sample of apparently healthy Korean adults. METHODS: This cross-sectional study analyzed data of 3189 community-dwelling people (1189 men and 2000 women) who were aged 40 to 87 years and were living in a rural area in Korea. Serum albumin levels were classified into quartile groups for each sex. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III guidelines with an adjusted waist circumference cut-off value (> or =90 cm for men and > or =85 cm for women). An independent association between serum albumin levels and metabolic syndrome was assessed by multiple logistic regression analysis. RESULTS: Higher serum albumin levels were associated with increased prevalence of metabolic syndrome. The odds ratio (95% confidence interval) of the prevalence of metabolic syndrome for the highest versus the lowest serum albumin quartiles was 2.81 (1.91 to 4.14) in men and 1.96 (1.52 to 2.52) in women, after adjusting for age, smoking status, alcohol consumption, and physical activity. When each metabolic abnormality was analyzed separately, higher serum albumin levels were significantly associated with hypertriglyceridemia and hyperglycemia in both sexes, and with abdominal obesity in men. CONCLUSIONS: These results suggest that higher serum albumin levels are positively associated with an increased risk of metabolic syndrome in Korean adults.

Spontaneous renal subcapsular hematoma is a rare, life-threatening condition that is usually caused by benign and malignant renal tumors, vascular diseases, inflammatory disorders, blood dyscrasias, and seldom suspected clinically. The characteristic clinical features are abdominal pain, a mass in the flank and signs of internal bleeding. Severe preeclampsia is also a major contributing factor of the renal hematoma. Because renal function is decreased in spontaneous renal subcapsular hematoma, physicians should be aware of the clinical symptoms and signs, appropriate investigation and management may be life-saving. This case of spontaneous renal subcapsular hematoma and acute renal failure complicated by severe preeclampsia, which occurred after delivery and was treated conservatively.

OBJECTIVES: Serum uric acid levels have been reported to be associated with a variety of cardiovascular conditions. However, the direct association between uric acid levels and metabolic syndrome remains controversial. Thus, we evaluated the association of serum uric acid levels and metabolic syndrome in a community-based cohort study in Korea. METHODS: We performed cross-sectional analysis of baseline data of 889 males and 1491 females (aged 38 to 87) who participated in baseline examinations of the Korean Genome and Epidemiology Study: Kanghwa study. Blood samples were collected after at least an 8 hour fast. Uric acid quartiles were defined as follows: <4.8, 4.8-<5.6, 5.6-<6.5, > or =6.5 mg/dL in males; and <3.8, 3.8-<4.3, 4.3-<5.1, > or =5.1 mg/dL in females. Metabolic syndrome was defined by the National Cholesterol Education Program Adult Treatment Panel III Criteria with adjusted waist circumference cutoffs (90 cm for males; 80 cm for females). The association between serum uric acid quartiles and metabolic syndrome was assessed using multivariate logistic regression. RESULTS: The odds ratio for having metabolic syndrome in the highest versus lowest quartiles of serum uric acid levels was 2.67 (95% confidence interval [CI], 1.60 to 4.46) in males and 2.14 (95% CI, 1.50 to 3.05) in females after adjusting for age, smoking, alcohol intake, body mass index, total cholesterol, HbA1c, albumin, gamma-glutamyltransferase, blood urea nitrogen, and log C-reactive protein. The number of metabolic abnormalities also increased gradually with increasing serum uric acid levels (adjusted p for trend < 0.001 in both sexes). CONCLUSIONS: Higher serum uric acid levels are positively associated with the presence of metabolic syndrome in Korean males and females.

BACKGROUND/AIMS: Sleep duration affects health in various ways. The objective of this study was to investigate the associations of sleep duration with chronic kidney disease (CKD) in a Korean adult population. METHODS: This cross-sectional analysis was conducted for total of 1,360 participants who completed baseline health examinations for the Korean Genome and Epidemiology Study-Kangwha study in 2010 to 2011. Sleep habits were measured by an interviewer-assisted questionnaire. Sleep duration was calculated based on the number of hours per day participants had slept over the past 1 year. CKD was defined as either proteinuria or estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m². Multiple logistic regression models were applied to examine associations between sleep duration and CKD. RESULTS: Women with very long sleep duration (≥ 9 hours/day) were at significantly increased odds for having high serum creatinine (odds ratio [OR], 2.936; 95% confidence interval [CI], 1.176 to 7.326), low eGFR (OR, 3.320; 95% CI, 1.372 to 8.034), and CKD (OR, 3.112; 95% CI, 1.315 to 7.363), compared those with a typical sleep duration (7 to < 8 hours/day), after adjusting for sociodemographic status, socioeconomic status, health behaviors, comorbidities, and sleep quality. Among women, for every 1 hour increase in sleep duration per day, there was a 24.6% increase in the presence of CKD (OR, 1.246; 95% CI, 1.019 to 1.523). However, among men, sleep duration was not significantly associated with CKD. CONCLUSIONS: Very long sleep duration was independently associated with a higher prevalence of CKD among Korean women. Gender may influence this association.
